cooxru'e APPARATUS.

To all whom it may concern:

Be it known that I, GEORGE *F. rumm- TON, a citizen of the United States, residing at Mattapoisett, in the-couny of Plymouth and State of Massachusetts, have invented certain new and useful Improvements in Cooking Apparatus; and I do hereby declare thefollowing to be a full, clear, and

exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This'invention relates to a machine for cooking of doughnuts, crullers, potatoes, or other articles .of food by submerging same in hot oil or grease. a The object of theinvention is to provide a simpleand efficient machine by means of which the process can be performed automatically, with greater accuracy, precision and rapidity and under more comfortable andsanitary conditions for the cook or op; erator.

The invention consists in the machine comprising the novel structure and combination hereinafter more fully described 5 Three sheets of drawings accompany this specification as a part thereof, in which like reference characters'denote like partsthroughout. i

Figure 1 is a side sectional view of the device.

Fig. 2 is a plan view with certainparts' shown in section.

Fig. 3 is a side sectional view of one end of the dev ce showing the carriage-1n its 7 forward position.

Fig. 4 is a perspective view of a drag member reinoved from the machine.

Fig.5 is a perspective view of the carriage and the slides therefor, removed from the machine. v

Referring to the drawings, the machine shown, adapted to handling two doughnuts at a time, comprises a substantially rectangular grease pan, of a depth sufficient to hold a suitable quantity of oil or grease, and to allow a reasonable clearance for the operation of the mechanism above the oil. Within the pan 1, and attached thereto at one end, is a U-shaped yoke member 18 carrying on the inner sides of its legs guide bars 23, and having a central partition 29, and a transverse bridge member 2'. Near the end of pan 1, bearings 6-6 are provided on each Specification of Letters Patent.

side, and in the bottom is secured a concave guide late 15.

In t e bearings 6-6 is mounted a shaft 5' provided with guide collars 6-6 and a driving sprocket 32, and carrying over and within pan 1, and on each side, sprocket wheels 7-7, suitably keyed orpinned to said shaft. Longitudinal frame members 3- 3 are providedat each end with T bearing members 4.-'4-'4-'4 and these members are supported at one end on shaft 5. These frame members'3-3 are also attached to bridge member 2' and are supported thereby and in turn support bridge member 2. Guide members '16..are supported from bridge member 2. .A shaft 5 is mounted in the T bearings 4-4 on the opposite ends of frame members 3-3 and supported thereby. On each end of shaft 5 are mounted the sprockets 8-8 and gear wheels 24, the latter having teeth 25, on half of their circumfer-- ence as shown in Figs. 1 and 3.

An endless chain ladder composed of links 9 and transverse bars 10 is mounted on and carried by the sprockets 7-7 and 88. On thisendless chain are mounted drag members 11 spaced a little more than a doughnuts diameter apart, and comprising fingers 19 and braces 13 secured to the bars 10 by overturned portions 14 and 14' and secured against transverse movement by collars 12.

A carriage having a drag member 30 com- I prising-fingers 20' and 21 and. two parallel rack bars 22-22 adapted to slide on guides 23 within yoke 18' is provided with a cord 26 which passes through a hole in-the back wheel 27 attached thereto and up'and over a guide wheel 27'. mounted on the rim of the pan 9 and has a suitable weight 28 attached to its end.

T The partially toothed gears 24 are adapted to engage the rack bars 22 as shown in Fig. 1, and to carry same forward until the last of teeth 25 passes out of engagement as shown in Fig. 3, whereupon the'carriage is released and the weight 28 operates to withdraw the carriage to its original position at the rear of the pan 1. I

In operation the doughnuts -'a-' are placed in the carriage as indicated in Figs. 1- and 2. Power applied to the sprocket 32 rotates sprockets 7-7 and '8-,8 by means of the endless chain. ladder an. when gears 24 have rotated sufficiently thei teeth 25 en-' gage rack bars 22 and advance the carriage.

the hot oil but of the device adapted to the character of the to be cooked or the numwith the doughnuts, the doughnuts being held by the. fin ers 20, between which the oil passes freely. hen the carriage reaches its forward positiona drag member'll mounted on the endless chain interposes and sweeps the doughnuts a forward off of the carriage. At the same timethe last of the teeth 25, is lifted from the rack bars 22 and the carriage is withdrawn for anew load.

The doughnut ais then carried continuously forward by drag 11, the oil passing freely formly down by the bars 10 and at the forward end of pan 1 is raised over the concave guide 15 and thrown out of pan 1 onto some .suitable chute 31; The doughnuts or other articles normally sink-when first placed in become buoyant at the point when the chain carrier supersedes the carriage.

The proportions of the device as well as justed in conjunction with the temperature of the oil to allow the proper periods for the various stages of the operation, by means of which the articles placed in the machine, uncooked, will be expelled thoroughly and properly cooked in all respects. By retaining the naturally buoyant articles submerged in the oil there is no necessity for turning and this operation in the ordlnary domestic process is entirely eliminated.

It will be obvious that many variations and modifications in the form and structure particu ar articles her to be cooked in any operation, gest themselves to those skilled in and will be embraced within the scope of this invention.

-What I claim is:

1. A machine for cooking doughnuts and the like comprising an open container for hot oil, a receiver slidably mounted in the will sug-v the art,

- container in submerged relation to the oil,
